JOHN BYINGTON, OF ST. CHARLES, MISSOURI.

DUST- EZXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 683,436, dated October 1, 1901.

Application filed September 15,1900. Serial No. 30,170- (No model.)

To all whom it may concern:

Be it known that LJOHN BYINGTON, a citizen of the United States, residing at St. Charles, in the county of St. Charles and State of Missouri, have invented a new and useful Dust- Extractor, of which the following is a specification.

This invention relates to improvements in dust-extractors; and the object is to provide an improved construction of dust-extractor bymeans of which the dust and dirt may be quickly and readily loosened and removed and conveyed to any desired point without scattering thereof and at the expenditure of out little labor.

With the above object in view the invention consists in the novel features of construction hereinafter fully described, particularly pointed out in the claim, and clearly illustrated by the accompanying drawings, in which Figure 1 is a perspective View of the brush employed in my invention; Fig. 2, a transverse sectional view of the same; Fig. 3, a vertical longitudinal sectional view 5 Fig. 4, a detail view of the valve, and Fig. 5 a diagrammatic view showing an arrangement for producing a current of air through the brush.

Referring now more particularly to the accompanying drawings, A designates the head of the brush, which is formed hollow and provided with the bristles B and adjacent to the bristles with perforations C. The brush is provided with a tubular handle D, which is screwed into or otherwise secured to the hol 10w head on the side opposite to that carrying the bristles. Positioned in the handle is a valve E, normally heldclosing the passage therethrough byaspring F and operated from the exterior of said handle. Attached to the end of the handle is a flexible tube G, which tube may be attached directly to the hollow head of the brush and carry a suitable valve. The opposite end of this tube is connected with a casing, in which a fan is positioned or in which a partial vacuum is produced, the latter being here illustrated.

In Fig. 5, H, I, and J designate vacuumcllambers, all of which are connected with a pipe K, to which the flexible tube is attached by means of pipes L, having valves L. M designates an air-pump connected with the vacuum-chambers by pipes N, in each of which a controlling-valve O is placed. By this arrangement a vacuum is produced in one of said chambers, and said chamber by opening the proper valves used in connection with the brush to induce a current of air therethrough. In the meantime the communication between the pump and the chamber in use can be closed and the pump used to produce a vacuum in another of said chambers, so that a chamber-will always be ready for use with the brush.

The construction above described is designed more especially for use in a city or large building, in which pipe K would serve as a main pipe and passed through the various rooms of a building or the streets of a city, with branch pipes leading into the various rooms or houses and buildings. The brushes would be connected to these branch pipes. The dirt and dust will be conveyed by the current of air induced through the brush to any desired point without scattering thereof and with very little labor. The brush can be made of any size and form, according to the work in hand.

The essential features of my invention are a brush having means for loosening the dirt and means in connection with the brush for inducing a current of air therethrough to carry off the dirt and dust.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A dust-extractor comprising a plurality of vacuum-chambers, vacuum-producing mechanism having a controlled communication with each of said chambers, abrush comprising a perforated hollow head provided with bristles, and a controlled communication between each of the vacuum-chambers and said brush, substantially as described.
